Chapter 4 Beneficiation of Gold and Silver Ores

Crushing is an important step in comminution that prepares the ROM ore for pri-mary grinding and other downstream processes such as heap leach. The selection of the right crushers and crusher flow sheet is dependent on the upstream mining method and blasting characteristics and the downstream process requirements. As
